Corrosion inhibitor acts of the graphite packing reinforced with metal wire as a sacrificial anode to protect the valve stem and the stuffing box.
Typical Application
> Flexible graphite packing is a multi-service packing capable of a wide variety of uses throughout a plant.
> It can be used in valves, pumps, expansion joints, mixers and agitators in high-pressure and temperature.
> Excellent for use in steam turbines, high temperature motor-actuated valves
> High temperature and high pressure valve applications in general.
Prime Features
> It can be reinforced with nickel, stainless steel, copper, etc.
> High pressure, high temperature
> Wide variety of uses throughout a plant
> Precaution: in oxidizing environment may use with SUNWELL 4**R anti-extrusion packing rings.
